for Java, you might use:

public String exceptionMessage(Exception exc, boolean includeStack) {
    String message = "[" + exc.getClass().getSimpleName() + "] " + (!includeStack ? exc.getMessage() : getStackTrace(exc));
    int length = Math.min(10000, message.length());
    return message.substring(0, length);
}

private String getStackTrace(Exception exc) {
    StringWriter sw = new StringWriter();
    PrintWriter pw = new PrintWriter(sw);
    exc.printStackTrace(pw);
    return sw.toString();
}
